Shoppers praise ‘luxurious’ hair serum for giving ‘thicker’ strands

Thinning hair and reduced density are common concerns that can affect confidence and styling options. Whether caused by stress, hormonal changes, or outside factors, many are seeking effective solutions to support healthier, fuller-looking hair.

That’s why targeted scalp treatments and advanced haircare formulas have become essential steps in routines foucsed on strengthening hair. Now, shoppers can get the L’Oreal Professional Serioxyl Advanced Desnity Activator Serum for £27.45 down from £48 on Amazon to hopefully help.

This serum is a targeted treatment designed to help tackle the signs of thinning hair. Formulated with 5% Stemoxydine – a powerful active ingredient known to support hair density – and antioxidant-rich Resveratrol, this serum works to promote a healthier scalp environment and encourage fuller hair over time.

With consistent daily use, the serum helps to increase the number of hairs, leaving scalps and roots feeling revitalised. The lightweight, leave-in formula is said to be easy to apply: simply part the hair into four sections, spray six times in each area, and gently massage in with fingertips. No rinising is required making it a seamless addition to an everyday haircare routine.

If this isn’t the one for everyone, shoppers could also try The Ordinary Multi-Peptide Serum for Hair Density for £20.80 from Boots which is lightweight and designed to support the scalp and give thicker and fuller-looking hair. Another is the Pitta grown serum from Champo for £46 which volumises roots while stimulating the scalp for fuller and stronger looking hair.

The serum has got a 4.5 out of 5 star rating on Amazon from over 500 reviews. One person said: “Overall I’m impressed. This hair treatment has not disappointed: more of a serum than an oil, this soaks into hair well without leaving any greasiness, oiliness or stickiness, yet hair still feels softer and thicker. Both my hair and scalp are nourished by this and the ingredients speak for themselves. A couple of drops is enough to see a difference but this is still quite expensive – a luxurious treat!”

Another said: “Great product from Loreal. very much affective for hair growth and thickness.”

Another reviewer said: “Amazing stuff. I’m in perimenopause and my already fine hair is thinning. This shampoo – along with the serum I use at night – is great. I saw a difference in look and feel for my extra fine hair almost immediately. Only thing apart from biotin supplements that has worked so far.”

Not everyone shared the same thoughts on the product, however, as one person said: “This is a hair product with an overpowering scent that rejuvenates the scalp and helps those with a fine to medium hair density get thicker hairs.”

“The bottle is a little small in size given the price, however the application is very easy and the scent isn’t overpowering. There has been some noticeable change in the density of my husbands hair, but it has also grown significantly faster,” said another.

The L’Oreal Professional Serioxyl Advanced Desnity Activator Serum is available from Amazon.
